Until the ATF declares the “buyback” = the Texan “selling” manufactured firearms with intent to profit without a manufacturer’s license.
But, the items were not firearms, just printed material that looked like a firearm....
A firearm is a legally described item. If it doesn’t walk, talk ANF look like a duck, it isn’t.
Turning them into the police to be destroyed is not “selling” them.

You can make guns for your own use but BY LAW those guns are NOT transferrable. The only way to make them transferrable is to get a Type 7 manufacturing license from the ATF, and follow all the same rules as the other firearms manufacturers, ... such as putting serial numbers on the guns.
And I doubt you'll see an anti-gun ATF let this opportunity pass because this guy's greater crime (in the ATF's eyes) will be depleting funds that could have been used to get real guns off the street. If they let this pass, random guys with a 3d printers will be drawn to all future gun buy-backs like flies are drawn to Hitlery Klinton's stasis ulcers and they'll spend all their buy-back bucks buying worthless plastic junk created specifically to suck up their funding.
